[0062] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0063] like Figures 1 to 8 As shown, a first aspect of the present invention provides a door assembly, including a first door body 100, a second door body 108, and an inflatable rubber 112; wherein, the first door body 100 is slidably mounted on a vehicle body, and a first lock box 102 is provided on the first door body 100, wherein one of a latch assembly 104 and a stop pin assembly 106 is provided in the first lock box 102; the second door body 108 is slidably mounted on the vehicle body, and a second lock box 110 is provided on the second door body 108, wherein the second lock box 110 is provided with a latch assembly 104 and a stop pin assembly 106; There is another of the latch assembly 104 and the stop pin assembly 106; the inflatable rubber 112 is disposed along the edge of the first door body 100 and the edge of the second door body 108; the first door body 100 and the second door body 108 are adapted to switch between an open state and a closed state, wherein in the open state, the latch assembly 104 and the stop pin assembly 106 are adapted to disengage from each other and the inflatable rubber 112 is adapted to deflate; and in the closed state, the latch assembly 104 and the stop pin assembly 106 are adapted to lock together and the inflatable rubber 112 is adapted to inflate.

[0064] According to the door assembly provided in the first aspect of the present invention, by providing a first lock box 102 and a second lock box 110 on a first door body 100 and a second door body 108, and configuring the first lock box 102 and the second lock box 110 in a form that adapts to the locking assembly 104 and the stop pin assembly 106, the locking assembly 104 and the stop pin assembly 106 can lock each other when the first door body 100 and the second door body 108 are closed. Simultaneously, the inflation of the inflatable adhesive 112 provided at the edges of the first door body 100 and the second door body 108 can improve the sealing performance of the first door body 100 and the second door body 108. When the first door body 100 and the second door body 108 are opened, the locking assembly 104 and the stop pin assembly 106 disengage, and the inflatable adhesive 112 deflates, without affecting the operation of the first door body 100 and the second door body 108. Furthermore, since the first door 100 and the second door 108 do not require a self-locking mechanism from a motor to achieve a limit, the large opening range of the first door 100 and the second door 108 becomes a reality.

[0065] Please continue reading Figures 1 to 8 In this embodiment of the invention, the first door 100 and the second door 108 can move along the length of the vehicle body to open or close the space inside the vehicle. That is, the first door 100 and the second door 108 can switch between an open state and a closed state. When the first door 100 and the second door 108 are in the open state, the space inside the vehicle is open; when the first door 100 and the second door 108 are in the closed state, the space inside the vehicle is closed.

[0066] A first lock box 102 is provided on the first door body 100, and a second lock box 110 is provided on the second door body 108. The first lock box 102 can house a latch assembly 104, and the second lock box 110 can house a stop pin assembly 106. When the first door body 100 and the second door body 108 are in the closed state, the latch assembly 104 and the stop pin assembly 106 are locked together to ensure that the first door body 100 and the second door body 108 are stably closed. At this time, to ensure the sealing performance between the first door body 100 and the second door body 108 and the vehicle body, the inflatable rubber 112 is simultaneously inflated. When the first door body 100 and the second door body 108 are in the open state, the latch assembly 104 and the stop pin assembly 106 disengage to allow the first door body 100 and the second door body 108 to move away from each other. At this time, to prevent the inflatable rubber 112 from affecting the operation of the first door body 100 and the second door body 108, the inflatable rubber 112 is deflated.

[0067] In this embodiment of the invention, the inflatable adhesive 112 is disposed along the edges of the first door body 100 and the second door body 108, respectively. To further improve the sealing performance, a brush is also disposed on one side of the inflatable adhesive 112.

[0068] According to one embodiment of the present invention, a first stop bar 142 is provided on the side of the first door 100 facing the second door 108, and a second stop bar 144 is provided on the side of the second door 108 facing the first door 100. When the first door 100 and the second door 108 are locked, the first stop bar 142 and the second stop bar 144 are adapted to be closely fitted to each other.

[0069] To further improve the sealing performance of the first door 100 and the second door 108 when closed, a first stop bar 142 is provided on the first door 100 and a second stop bar 144 is provided on the second door 108. At this time, the first stop bar 142 and the second stop bar 144 are closely fitted to each other.

[0070] In some other embodiments, in order to achieve buffering when the first door 100 and the second door 108 are opened, buffering structures, such as baffles, are respectively provided on the side of the first door 100 away from the second door 108 and on the side of the second door 108 away from the first door 100.

[0071] According to one embodiment of the present invention, protective plates are respectively provided on the side of the first door 100 and the second door 108 facing the vehicle body. That is, special protective plates are laid inside the first door 100 and the second door 108, which can play a role in bulletproof protection.

[0072] See Figure 2 According to one embodiment of the present invention, the stop pin assembly 106 includes a lever plate 114, an arc-shaped connecting plate 116, and a locking hook 118; wherein, the lever plate 114 is rotatably mounted on the second lock box 110; the first end of the arc-shaped connecting plate 116 is rotatably connected to one end of the lever plate 114, and the arc-shaped connecting plate 116 is bent toward the first lock box 102; the first end of the locking hook 118 is rotatably mounted on the second lock box 110, the second end of the locking hook 118 forms a locking hook 118 portion, and the second end of the arc-shaped connecting plate 116 is connected between the first end of the locking hook 118 and the second end of the locking hook 118.

[0073] Please continue reading Figure 1 and Figure 2 A latch assembly 104 and a stop pin assembly 106 are respectively installed in the middle of the first door body 100 and the middle of the second door body 108. Specifically, two stop pin assemblies 106 are installed in the middle of each of the first door body 100 and the second door body 108. When a door malfunctions during vehicle operation, the locking of the first lock box 102 and the second lock box 110 can isolate the door and maintain normal vehicle operation.

[0074] In this embodiment of the invention, the stop pin assembly 106 is a dual-position dead-point device. The arc-shaped connecting plate 116 connects the lever plate 114 and the lower locking hook 118, and the linkage between the upper and lower locking hooks 118 is achieved through the linkage rod. With this setting, the locking action can be completed by the two isolated locking contacts at the top and bottom of the door from one point.

[0075] When isolating and locking, the outer lock cylinder of the door is rotated, which causes the lever 114 to rotate at a certain angle. At the same time, the arc-shaped connecting plate 116 transmits the rotation of the lever 114 to the lower lock hook 118, so that the lower lock hook 118 rotates from the unlocked position to the locked position. The curved front end of the lower lock hook 118 contacts the lower latch assembly 104, forming an isolating and locking mechanism. The lower locking hook 118 is connected to the upper locking hook 118 via a linkage rod, enabling coordinated operation. When locking, the upper locking hook 118 contacts the upper stop pin assembly 106, adding an isolation locking contact point for the wide-opening door, ensuring the smoothness and reliability of the wide-opening double doors. In the locked and unlocked positions, the lower locking hook 118 is in the dead point position, meaning that unlocking and locking operations cannot be performed from inside the vehicle body and can only be performed from outside the vehicle body using a key. This avoids accidental unlocking operations caused from inside the door while the vehicle is in motion. This device ensures that the isolation locking hook 118 is in the over-dead point position when unlocking and locking, effectively resisting unlocking or lock skipping problems that occur during door movement. Furthermore, the entire unlocking device does not require additional positioning and limiting devices, simplifying the isolation locking operation.

[0076] According to one embodiment of the present invention, there are at least two first lock boxes 102, and at least two first lock boxes 102 are arranged at intervals along the height direction of the first door body 100; the second lock box 110 is arranged in a one-to-one correspondence with the first lock box 102 on the second door body 108; and a connecting rod is provided between two adjacent lock hooks 118.

[0077] As mentioned earlier, at least two first lock boxes 102 and two second lock boxes 110 are provided. Taking two as an example, the first lock boxes 102 are spaced apart along the height direction of the first door body 100, and the second lock boxes 110 are spaced apart along the height direction of the second door body 108. This arrangement makes the connection between the first door body 100 and the second door body 108 more stable.

[0078] According to one embodiment of the present invention, a clamping and locking device is further included, which includes a mounting plate 122, an active member 124, and a pressure rod 126; wherein, the mounting plate 122 is mounted on the vehicle body; the active member 124 is rotatably mounted on the mounting plate 122; the first end of the pressure rod 126 is rotatably mounted on the mounting plate 122, and the connection position between the first end of the pressure rod 126 and the mounting plate 122 is offset from the plane where the first door 100 and the second door 108 are located; the second end of the pressure rod 126 is provided with a clamping member; and the output end of the active member 124 is rotatably connected to the pressure rod 126.

[0079] Please see Figure 3 and Figure 4 In this embodiment of the invention, to further improve the stability of the first door 100 and the second door 108 when closed, the door assembly also includes a clamping and locking device. By providing the clamping and locking device, when the first door 100 and the second door 108 are in the closed state, the stability of the first door 100 and the second door 108 can be further improved by the clamping and locking device, preventing deformation of the first door 100 and the second door 108.

[0080] like Figure 4 As shown, a mounting plate 122 is provided on the vehicle body, and an active component 124 is provided on the mounting plate 122. The active component 124 can be a cylinder, with its cylinder body rotatably connected to the mounting plate 122. The first end of a pressure rod 126 is rotatably mounted on the mounting plate 122. Furthermore, the connection position between the first end of the pressure rod 126 and the mounting plate 122 is offset from the plane containing the first door 100 and the second door 108. It can be understood that a relatively small angle is formed between the pressure rod 126 and the first door 100 and the second door 108. A clamping element, which can be a clamping block, is provided at the second end of the pressure rod 126. With this arrangement, when the active component 124 extends, the second end of the pressure rod 126 moves the clamping element away from the first door 100 and the second door 108; when the active component 124 retracts, the second end of the pressure rod 126 moves the clamping element closer to the first door 100 and the second door 108. That is, this allows for longitudinal compression of the first door 100 and the second door 108, and also allows for lateral compression of the first door 100 and the second door 108 along a direction perpendicular to the vehicle body.

[0081] According to one embodiment of the present invention, a guiding device is further included, which includes a guide rail and a mounting base 134. The guide rail is mounted on the vehicle body and includes a first guide section 128 perpendicular to the first door 100 and the second door 108 and a second guide section 130 connected to the first guide section 128. A guide groove 132 is formed on the second guide section 130 and extends along the length direction of the vehicle body. The mounting base 134 is mounted on the first door 100 and the second door 108 and is provided with a first guide wheel 136, a second guide wheel 138 and a third guide wheel 140. The first guide wheel 136 and the second guide wheel 138 are respectively disposed on the upper and lower surfaces of the first guide section 128, and the third guide wheel 140 is disposed in the guide groove 132.

[0082] like Figure 7 and Figure 8 As shown, to improve the stability of the first door 100 and the second door 108 during movement, a guide rail is provided on the vehicle body, which extends along the length of the vehicle body. In this embodiment of the invention, the guide rail includes a first guide section 128 and a second guide section 130, wherein the first guide section 128 extends along the length of the vehicle body, and a guide groove 132 is formed on the second guide section 130, which also extends along the length of the vehicle body.

[0083] The first guide section 128 is used to cooperate with the first guide wheel 136 and the second guide wheel 138, which are located on the upper and lower surfaces of the first guide section 128, respectively. In this embodiment of the invention, the first guide wheel 136 can prevent the first door 100 and the second door 108 from jumping, and the second guide wheel 138 can reduce the moving friction of the first door 100 and the second door 108. The third guide wheel 140, through cooperation with the guide groove 132, can prevent the first door 100 and the second door 108 from swaying in a direction perpendicular to the vehicle body. Thus, the stability of the first door 100 and the second door 108 during movement can be improved through the above-mentioned arrangement.

[0084] According to one embodiment of the present invention, it further includes a load-bearing drive device, which includes a drive member and a transmission member; the drive member is mounted on the vehicle body; the transmission member is drively connected between the drive member and the first door 100 and the second door 108.

[0085] In this embodiment of the invention, the driving component can be a motor, which is mounted on the vehicle body. A transmission component, such as a timing belt, is provided between the motor and the first door 100 and the second door 108. To prevent the timing belt from slackening, a tensioning pulley can also be provided at the location of the timing belt.

[0086] like Figure 1As shown, the load-bearing drive unit is connected to the vehicle body by bolts. The load-bearing drive unit mainly includes a drive component and a transmission component. The drive component is mounted on the mounting base 134. As mentioned earlier, the mounting base 134 is used to fix the guide rail and prevent the guide rail from deforming under stress. The drive component is mounted on the mounting base 134 and uses a synchronous belt to achieve transmission.

[0087] In this embodiment of the invention, the drive unit forms a carrying trolley on the mounting base 134. Each carrying trolley has two sets of carrying wheel assemblies inside. The carrying wheel assemblies are of a floating design, and the two carrying wheels can rotate around the axis to ensure that the carrying wheels always remain in contact with the guide rail during long-distance movement, thereby ensuring that the carrying device is subjected to balanced force during the movement of the door. Under the control of the controller, the drive unit can drive the transmission component connected to it to move, thereby driving the first door 100 and the second door 108 to open and close the doors along the direction of the guide wheel movement. The opening degree of the first door 100 and the second door 108 can reach more than 6 meters.

[0088] According to one embodiment of the present invention, a limiting member is also included, which is installed on the vehicle body. When the limiting member is triggered by the first door 100 and the second door 108, the driving member stops.

[0089] In this embodiment of the invention, a limiting component is provided on the vehicle body. The limiting component can be a proximity switch, etc. Taking the first door 100 as an example, when the first door 100 is opened, after opening to a preset position, the driving component stops to prevent the first door 100 from over-positioning. Similarly, when the first door 100 is closed, after closing to a preset position, the driving component stops to prevent the first door 100 from over-positioning.

[0090] A second aspect of the present invention provides a rail vehicle, including a vehicle body and the aforementioned door assembly.

[0091] According to the second aspect of the present invention, the rail vehicle provided can achieve a large opening degree of the first door 100 and the second door 108 by setting the above-mentioned door assembly, and can also improve the stability of the first door 100 and the second door 108 during the opening and closing process.

[0092] The rail vehicles mentioned here can be those used for freight trains, etc.

[0093] like Figure 9 As shown, a third aspect of the present invention provides a control method based on the above-described door assembly, comprising:

[0094] Step 10: Obtain the first state information of the first door 100;

[0095] Step 20: Obtain the second state information of the second door 108;

[0096] Step 30: Based on the first state information and the second state information, determine the relative motion mode of the first door body 100 and the second door body 108, and determine the inflation state of the inflatable glue 112.

[0097] According to the control method of the door assembly provided in the third aspect embodiment of the present invention, by acquiring the first state information of the first door body 100 and the second state information of the second door body 108, and adjusting the relative motion mode of the first door body 100 and the second door body 108 based on the first state information and the second state information, and determining the inflation state of the inflatable adhesive 112, effective control of the first door body 100 and the second door body 108 and effective sealing of the first door body 100 and the second door body 108 can be achieved.

[0098] In step 10, the first state information of the first door 100 can be obtained by the sensor. The first state information may be the motion state of the first door 100 or the distance between the first door 100 and the vehicle body.

[0099] Similarly, in step 20, the second state information of the second door 108 can be obtained by the sensor. The second state information can be the motion state of the second door 108 or the distance between the second door 108 and the vehicle body.

[0100] In step 30, the movement modes of the first door 100 and the second door 108 can be determined by the first state information and the second state information obtained in steps 10 and 20, and the inflation state of the inflatable rubber 112 can also be determined.

[0101] According to an embodiment of the present invention, the step of determining the relative motion pattern of the first door body 100 and the second door body 108 includes:

[0102] The first state information indicates whether the first door 100 is closed or open, and the second state information indicates whether the second door 108 is not closed or open. The second door 108 is then controlled to perform an action opposite to the current action.

[0103] Understandably, in this step, when the door opens, the door control module determines whether the door position signal exceeds a given threshold. If the door signal does not exceed the given threshold within a given time, the door control module determines that the door has encountered an obstacle.

[0104] In this embodiment of the invention, the door control module can transmit independent control signals to the first door 100 and the second door 108. During the opening process, when the door control module determines that both the first door 100 and the second door 108 have encountered obstacles, both the first door 100 and the second door 108 return to the closed position. During the opening process, when the door control module determines that the first door 100 has encountered an opening obstacle, the first door 100 returns to the closed position, while the second door 108, which has not encountered an obstacle, continues to open to the correct position.

[0105] When closing the door, the door control module needs to simultaneously determine the position signals of the first door 100 and the second door 108, as well as the closed / locked switch signals of the first door 100 and the second door 108. When the first door 100 and the second door 108 are in the closed / locked position, the closed / locked switch is triggered, thus determining that the first door 100 and the second door 108 are closed / locked. If the first door 100 and the second door 108 are not in the closed / locked position, or if either the closed or locked position is not triggered, a closing obstacle is diagnosed. When the first door 100 diagnoses a closing obstacle detection event, if the second door 108 is not in the closed / locked position, both the first door 100 and the second door 108 will open to the open position simultaneously; if the second door 108 is already in the closed / locked position, only the first door 100 will open to the open position.

[0106] According to one embodiment of the present invention, it further includes:

[0107] Based on the first state information and the second state information, the actual speed deviation between the first door 100 and the second door 108 is determined.

[0108] Based on the actual speed deviation, the operating speeds of the first gate 100 and the second gate 108 are corrected.

[0109] It is understandable that in this step, the first door 100 and the second door 108 each have two different sets of driving components. When the door control module controls the two driving components, there is a sequence in the software. In addition, the resistance of the first door 100 and the second door 108 is not exactly the same. Therefore, the movement positions of the first door 100 and the second door 108 will be different during the opening and closing process.

[0110] The door control module receives the motor position signals from the first door 100 and the second door 108, and uses them to obtain the positions of the first door 100 and the second door 108. When the position deviation exceeds the set range, speed correction is performed to ensure that there is no significant difference in the time when the first door 100 and the second door 108 reach the door opening and closing position.

[0111] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
